To all whom it may concern r Be it known that I, Josnrrr C. GOODMAN,

a citizen of the United States of America,

in the ventilator to be now described with respect to theaccoinpanyingjdrawing, which forms a which, i

Figure 1 is a front elevation,

Fig. 2 is a horizontal section therethrough,

Fig. 3 is a rear elevation,

Fig. l is a vertical cross sectiontaken on line 4. l of Fig. 2, I

Figs. 5 and 6 are horizontal sections showing the rear adjustableclosure in different positions,

Figs. 7 and 8 are respectively a partial front elevation and a verticalsection through a slightly modified form,

Fig. 9 is a front elevation-showing an extended form of the unitconstruction Fig. 1, and

Fig. 10 is a diagramillustrating the application of the ventilator to acar.

Referring now to these figures and particularly to Figs. 1 to 6inclusive my invention proposes a ventilator which includes arectangular casing 10 having top, bottom and side walls, which is openat its rear and is provided at its front with a wall 11 extending onlypartly thereacross from one of the side walls 12.. Adjacent to the frontis an air controlling member consisting of a plate 13 having a revertingflange 1e and a rounded portion 15 connecting the plate and flange andforming in the angle between the same a pocket. The plate 13 is mountedbetween the top and base of the casing 10 with its rounded portion 15adjacent to one side wall 12 and with its free edge and the free edge ofits flange 14 overlapping the free edge of the partial front wall 11'and dis-' posed in spaced relation thereto and respec tively within andbeyond the same.

rounded portion 15 partially extends beyond the front ofthe casing sothat'cinders, dust and the like checked by virtue of the tortuous pathit is thus necessary for the air to take through the ventilator, maydrop be low the same.

At its rear portion the top and base of the casing. havelongitudinalguideways 16 in which an adjustable closure is slidablymounted, this closure consistingof plates 17 and 18 havinghandles 19 andthus shift able to ether toward either end of the casin for controllingthe passage of air in the open position lSWlll be seen by acoinpar sonOf'Figs. 2 and 5, as well as independently shiftabletoward therelatively opposite ends of the casing to the closed position as seen inF 1g. 6, it being obvious that the air iscaused to "traverse a moretortuous path with the with the parts in the position of Fig.2.

In either instance air passing inwardly between the flange 14: and thepartial front like andinthis way separate the same from the air stream.J i

The construction as" thus outlined constiseries' of three controllingmembers at 20 operatively included to control the passage of air throughseparate compartments of a casing 21, in each of the compartments ofwhich the respective member is disposed in relation to the other partsas described in connection with Figs. 1 to 6 inclusive.

In Figs. 7 and 8 I have shown horizontally extending air controllingmembers 22 in a casing 23, located to control the passage of air througha series of compartments at the rear portions of each of which is avertically movable sliding closure 24 of the construction previouslydescribed In Fig. 10 I have shown diagrammatically the useof myinvention in reversed relation at relatively opposite ends of a car 25,the ventilators at each end being turned so as to tutes unit and variousnumbersofthese units may be employed depending upon the In Fig. 9 Ihaveshown a take in air at the front end of the car with respect to itsdirection of movement, when proceeding in either d1rect1on,theoppositely turned rear ventllator operating to exhaust air from the carunder the influence of currents of air proceeding along the car side. Inthis way it is obvious that when moving in either direction theventilator permits air to be taken in the front of the car andex- Vhausted by a vacuum at the rear of the car.

With either of the forms of the invention shown and described ity isfurthermore ob.-

vious air will be taken into the car at its front and expelled therefromat its rear so that effective and efficient ventilation issecured. Asshown in the diagram the form of'theimultiple ventilator of .9 be

utilized but it is equally obvious that the ventilator of Figs. 1 to 6inclusive may used or a greater degree ofv multiplication resorted to,depending upon conditions of 7 use a'nd the requirements.
